Disable double-tap zoom option in browser on touch devices

Question

I want to disable the double-tap zoom functionality on specified elements in the browser  on touch devices   without disabling all the zoom functionality   For example  One element can be tapped multiple times for something to happen  This works fine on desktop browsers  as expected   but on touch device browsers  it will zoom in

I know this may be old  but I found a solution that worked perfectly for me  No need for crazy meta tags and stopping content zooming    I m not 100  sure how cross-device it is  but it worked exactly how I wanted to         no-zoom   bind  touchend   function e      e preventDefault         Add your code here       this  click         This line still calls the standard click event  in case the user needs to interact with the element that is being clicked on  but still avoids zooming in cases of double clicking         This will simply disable the normal tapping function  and then call a standard click event again  This prevents the mobile device from zooming  but otherwise functions as normal   EDIT  This has now been time-tested and running in a couple live apps  Seems to be 100  cross-browser and platform  The above code should work as a copy-paste solution for most cases  unless you want custom behavior before the click event

If you need a version that works without jQuery  I modified Wouter Konecny s answer  which was also created by modifying this gist by Johan Sundstr  m  to use vanilla JavaScript   function preventZoom e      var t2   e timeStamp    var t1   e currentTarget dataset lastTouch    t2    var dt   t2 - t1    var fingers   e touches length    e currentTarget dataset lastTouch   t2     if   dt    dt  gt  500    fingers  gt  1  return     not double-tap    e preventDefault      e target click        Then add an event handler on touchstart that calls this function   myButton addEventListener  touchstart   preventZoom

I assume that I do have a  lt div gt  input container area with text  sliders and buttons in it  and want to inhibit accidental double-taps in that  lt div gt   The following does not inhibit zooming on the input area  and it does not relate to double-tap and zooming outside my  lt div gt  area  There are variations depending on the browser app   I just tried it     1  For Safari on iOS  and Chrome on Android  and is the preferred method  Works except for Internet app on Samsung  where it disables double-taps not on the full  lt div gt   but at least on elements that handle taps  It returns return false  with exception on text and range inputs      selector of  lt div gt  input area   on  touchend  disabledoubletap    function disabledoubletap ev         var preventok   ev target  is  input type text  input type range          if preventok  false  return false        2  Optionally for built-in Internet app on Android  5 1  Samsung   inhibits double-taps on the  lt div gt   but inhibits zooming on the  lt div gt       selector of  lt div gt  input area   on  touchstart touchend  disabledoubletap      3  For Chrome on Android 5 1  disables double-tap at all  does not inhibit zooming  and does nothing about double-tap in the other browsers  The double-tap-inhibiting of the  lt meta name  viewport      gt  is irritating  because  lt meta name  viewport      gt  seems good practice    lt meta name  viewport  content  width device-width  initial-scale 1             maximum-scale 5  user-scalable yes  gt

This will prevent double tap zoom on elements in  body  this can be changed to any other selector     body   bind  touchstart   function preventZoom e               var t2   e timeStamp              var t1     this  data  lastTouch      t2              var dt   t2 - t1              var fingers   e originalEvent touches length                this  data  lastTouch   t2               if   dt    dt  gt  500    fingers  gt  1                   return     not double-tap                           e preventDefault       double tap - prevent the zoom                also synthesize click events we just swallowed up               e target  trigger  click           But this also prevented my click event from triggering when clicked multiple times so i had to bind a another event to trigger the events on multiple clicks      selector   bind  touchstart click   preventZoom e            e stopPropagation      stops propagation     if e type     touchstart              Handle touchstart event        else if e type     click              Handle click event              On touchstart i added the code to prevent the zoom and trigger a click       selector   bind  touchstart  click   function preventZoom e               e stopPropagation      stops propagation             if e type     touchstart                        Handle touchstart event                  var t2   e timeStamp                  var t1     this  data  lastTouch      t2                  var dt   t2 - t1                  var fingers   e originalEvent touches length                    this  data  lastTouch   t2                     if   dt    dt  gt  500    fingers  gt  1                       return     not double-tap                                    e preventDefault       double tap - prevent the zoom                    also synthesize click events we just swallowed up                   e target  trigger  click                   else if e type     click                        Handle click event                  Put your events for click and touchstart here

Note  as of 2020-08-04   this solution does not appear to work in iOS Safari v12   I will update this answer and delete this note once I find a clear solution that covers iOS Safari  CSS-only solution Add touch-action  manipulation to any element on which you want to disable double tap zoom  like with the following disable-dbl-tap-zoom class   disable-dbl-tap-zoom     touch-action  manipulation     From the touch-action docs  emphasis mine    manipulation Enable panning and pinch zoom gestures  but disable additional non-standard gestures such as double-tap to zoom   This value works on Android and on iOS

Simple prevent the default behavior of click  dblclick or touchend events will disable the zoom functionality   If you have already a callback on one of this events just call a event preventDefault
